2635607

Description: SM timeouts on PortInfo MAD SET may occur when Operational VLs are decreased (for example, when running different SM with different op_vl configuration) due to wrong logic in firmware of buffers allocation per VL. The fix is to first handle the VLs needed to be decreased in size and then enlarge the ones needed to increase in size.
